Background: Cystic Fibrosis (CF) is one of the most common autosomal recessive genetic disorders, with the majority of patients born to couples unaware of their carrier status. Carrier screenings might help reducing the incidence of CF. Methods: We used a semi-automated reverse-dot blot assay identifying the 47 most common CFTR gene mutations followed by DGGE/dHPLC analysis. Results: Results of a 10-year (1996-2006) CF carrier screening on 57,999 individuals with no prior family history of CF are reported. Of these, 25,104 were couples and 7791 singles, with 77.9% from the Italian Veneto region. CFTR mutations were found in 1879 carriers (frequency 1/31), with DeltaF508 being the most common (42.6%). Subjects undergoing medically assisted reproduction (MAR) had significantly (p<0.0001) higher CF carrier frequency (1/22 vs 1/32) compared to non-MAR subjects. Conclusions: If coupled to counselling programmes, CF carrier screening tests might help reducing the CF incidence.

Abstract
Background: Cystic Fibrosis (CF) is one of the most common autosomal recessive genetic disorders, with the majority of patients born to couples unaware of their carrier status. Carrier screenings might help reducing the incidence of CF.Methods: We used a semi-automated reverse-dot blot assay identifying the 47 most corm-non CFTR gene mutations followed by DGGE/dHPLC analysis.Results: Results of a 10-year (1996-2006) CF carrier screening on 57,999 individuals with no prior family history of CF are reported. Of these, 25,104 were couples and 7791 singles, with 77.9% from the Italian Veneto region. CFTR mutations were found in 1879 carriers (frequency 1/31), with Delta F508 being the most common (42.6%). Subjects undergoing medically assisted reproduction (MAR) had significantly (p < 0.0001) higher CF carrier frequency (1/22 vs 1/32) compared to non-MAR subjects.Conclusions: If coupled to counselling programmes, CF carrier screening tests might help reducing the CF incidence.
